Ok, just took my '84 Omni (2.2l carb, 3-spd auto) through NJ inspection and failed the high-idle test:
Standing Idle:
HC ppm 28 (220 allowed)
CO% 0.53 (1.20 allowed)
CO2% 14.3
O2% 0.9
High Idle:
HC ppm 88 (220 allowed)
CO% 4.65 (1.20 allowed)
CO2% 12.1
O2% 0.2
All the secondary tests passed (even the original gas cap still passes!), but the High-idle CO is the issue.
I could have sworn I'd be able to search up some troublehsooting threads for this, but apparently my search-fu is lacking today. Can I get a point in the right direction?
Thanks,
Rob
